A Mexican magazine wholesaler owned by the Televisa conglomerate refused to distribute last month's copies of Zócalo magazine because it carried an article critical of Televisa.

The magazine's cover story was headlined "Does television elect presidents?" Its image, as shown here, was a version of the Televisa logo in the form of a dinosaur egg, with the emerging silhouette of the winning candidate, Enrique Peña Nieto.

Televisa's distribution company, Intermex, failed to supply copies of the August issue of Zócalo to more than 160 branches of one of the country's major magazine retailers.

The Paris-based press freedom body, Reporters Without Borders, said the refusal to distribute the magazine amounted to censorship. It called for an independent investigation into the blocking of distribution.
